Robust Trapdoor Tarantula (Haploclastus validus) The genus Haploclastus is endemic to India and is represented by six species. One of the species H. validus Pocock, 1899 was described from Matheran and has remained poorly known in terms of its natural history and distribution. During recent surveys the species was for the first time found again since its description nearly 110 years ago. Based on the new material collected it is redescribed and data on its natural history and distribution are added. It is the first record of an Indian theraphosid spider, which closes its burrow with a trapdoor.<br />

  4. From today's JungleDragon Facebook post:

    "Instead of weaving webs, Robust Trapdoor Tarantulas (Haploclastus validus) build silk-lined burrows that they cap with a trapdoor, which is hinged on one side. The entrance of the burrow is camouflaged by bits of twigs and gravel that the spider glues to the door with silk. They also lay out trip lines made of silk that serve as an alarm. The spiders are nocturnal, and they lurk behind the door at night, holding it in place with their legs, and wait for an insect to pass by and trigger the alarm. When prey is detected, the spider flings the door open, jumps out, grabs the prey, bites it, and shoves it down into their burrow. They are so fast, that this can happen in the blink of an eye.

    Trapdoor tarantulas are homebodies - the females never leave their burrows, and the males only leave theirs to seek a mate. This is amazing considering females can live for 30 years! The males, however, don't have much luck with longevity. They live for 5-7 years, mate, and then die. Since mating takes place within the female's burrow, the male's life often ends directly afterwards unless he is fast enough to escape before his partner eats him. A female must work hard to maintain and protect her burrow (even from her mate) because if gets damaged, she cannot rebuild or relocate. So, she never leaves it during her long life and instead makes the most of whatever resources come her way - wasting nothing and reusing whatever she can. This is surely a good example for humans on sustainable living! {Spotted in India by JungleDragon user, nightjar6} #JungleDragon"
